A Study on Suicidal Risk Analysis
ABSTRACT Assessment of suicidal risk factors is an interesting issue to deal with. The present paper is a novel attempt to analyze the factors largely encountered in a suicide scenario. Pierce suicidal intent scale (PSIS) has been chosen to capture the said factors, each having two levels, i.e., moderately or severely present in such a scene as depicted in PSIS. Risk levels (the responses) are also assessed in two levels - moderate and severe risks. A group of patients (irrespective of age, sex, social status, occupations, and any associated illnesses they are chronically suffering from) has been selected for this study with a history of previous suicide- attempt. An experimental design has been created using Plackett-Burman design (PBD) and the relationships among the factors and the responses are statistically determined using multiple regression analysis. It is observed that the risk of committing suicide largely depends on (i) the timing so that none can interfere the act, (ii) acting with clear intention of killing oneself and is premeditated, (iii) the act is so severe that revival with medical attention is quite unlikely, and (iv) the outcome of the act is predictable, i.e., death is the usual outcome. On the other hand, past history of suicide attempt has not added any significant risk, though it is thought to be an important contributor. Such findings could be useful to get seriously identified to the care-givers of those who may attempt suicide during their lifetime. Finally, the performance of the model is validated with the help of a set of real test cases and found to be good in prediction.

Article: Suicidal intent in self-injury.[show abstract] [hide abstract]
ABSTRACT: The difficulties in measuring suicidal intent in cases of self-injury are discussed, and a scale is described to measure this intent. This scale has been used in 500 cases of self-injury. It is practical and reliable. Results show that the scores derived from it are closely related to the similar Beck Scale; they are also related to age, sex, social isolation method of self-injury, previous history of self-injury or of psychiatric treatment, physical health at the time of self-injury and alcohol abuse. These results are discussed with particular reference to suicide prediction and the future validation of the scale by long-term follow-up.The British Journal of Psychiatry 05/1977; 130:377-85. · 6.61 Impact Factor
Article: [Depression and suicide].[show abstract] [hide abstract]
ABSTRACT: Depression is the most common psychiatric disorder in the general community. Depression is accompanied with the highest suicide risk. 3 % to 4 % of all depressives die by suicide even today. Suicide prevention is an important part of diagnostics, therapy, the long-term treatment, and care of depressed patients. Psychotherapeutic and psychopharmacological aspects must be included.Bundesgesundheitsblatt - Gesundheitsforschung - Gesundheitsschutz 05/2008; 51(4):443-50. · 0.72 Impact Factor
